A downstream packet that contains a DSCP value arrives at the WLC Ethernet interface from the wired source network. The WLC is configured for QoS WLAN 802.1p mapping. How does the WLC treat the CAPWAP QoS marking when leaving the controller interface for the respective AP and final wireless client destination?

No outer CAPWAP or inner QoS tagging is applied.

The outer CAPWAP CoS is marked and capped and the inner DSCP maintains the original marking.

No outer CAPWAP QoS tag is applied, but the original DSCP is maintained inside CAPWAP.

The outer CAPWAP DHCP is marked and capped without any inner DSCP value.

Refer to the exhibit.

While testing the post-deployment WLAN network, you discover that an AP has been placed in a difficult area.

The AP cannot be moved easily because of various requirements. The client performance of various Apple and Microsoft operating system-based products does not meet expectations. Which two options can help mitigate the performance issue? (Choose two.)

Add additional APs.

Increase the AP power level to maximum.

Rotate the AP 90 degrees to change antenna polarity.

Replace the AP with an AP and external antenna.

Change the AP location to one that is less RF hostile.

An engineer is deploying centralized wireless solution with a 5508 controller. What is the most AP licenses that can be supported?

A. 100

B. 250

C. 1000

D. 500

Answer: D Explanation:

You can order Cisco 5500 Series Controllers with support for 12, 25, 50, 100, 250 or 500 APs as the controller#39;s base capacity. You can add additional AP capacity through capacity adder licenses available at 25, 50, 100 and 250 AP capacities. You can add the capacity adder licenses to any base license in any combination to arrive at the maximum capacity of 500 APs.
